SPECIFICATION forming part of Letters Patent No. 448,716, dated March24, 1891.

Application filed November Z4, 1890. Serial No. 372,446. (No model.)

To @ZZ whom, t may concern:

Be it known that I, JOHN S. HILLIARD, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain neu7 and usefulImprovements in a Combined Cyclometer and Time-Piece, of which thefollowing is a specification.

My invention relates to a combined instrument for recording the distancetraversed by a vehicle-such, for example, as a bicycle or tricycle-andfor indicating time.

The principal objects of my present invention are, rst, to provide asimple, compact, and comparatively inexpensive instrument comprising acombined cyclometer and clock, and especially adapted foi-attachment tothe front forli of a bicycle ortricycle beneath the steering-headthereof, so as to be in plain sight of the rider at all times, and,second, to provide simple and efcient means for imparting motion to thecombined instrument from the periphery of the driving-Wheel instead offrom the center or from the axle thereof.

My invention consists of a device constructed, arranged, and adapted foroperation in the manner hereinafter described, and pointed out in theclaims.

The nature and objects of my present invention Will be more fullyunderstood from the following description, taken in connection With theaccompanying drawings, forming part hereof, and in Which-` Figure l is atop or plan view, partly in section, of portions of the front fork andfront Wheel of a bicycle or tricycle or other type of velocipede,showing the combined cyclometer and clock attached to the front forkabove the periphery of the Wheel and occupying an unobstructed positionin the sight of Jthe rider at all times. Fig. 2 is a horizontal sectionon the line 2 2 of Fig. 4:. Fig. Sis a similar sectional view on theline 3 3 of Fig. 4t; and Fig. 4. is a side view, partly in centralsection, of Fig. l.

In the drawings, A is the front forli of a bicycle, trioycle, or othertype of velocipede.

B is the tire of the driving or pilot wheel thereof.

ZL is a lng or projection attached to and extending laterally from thetire of the Wheel B and adapted to contact with and operate the lever eonce in each revolution of the Wheel B, for a purpose to be presentlyfully described.

e is a case or housing provided with a cap e2, a face c4, a glass covere, and apartition e3, havin gthe central portion thereof cutaway.

e6 is a sleeve secured to the face c'l and partition e3. This sleevecarries the lever e. and also an operating ratchet-wheel g, providedwith a finger (Z, extending through the central portion of the partitione3. rlhis lever e is held normally in position by means of a spring s,attached thereto and to the housing.

fis a spring-actuated pawl attached to the lever e and adapted to engagewith and advance one tooth of the operating ratchet- Wheel g at eachreciprocation of the lever, and consequently at each revolution of theWheel B.

e7 is a detent adapted to engage the teeth of the Wheel g in order toprevent the same from being accidentally or otherwise turned backward.

a is a crown-Wheel normally retained in position by means of a detent aand adapted to mesh With the finger (Z, and to be advanced thereby onetooth for each revolution of the ratchet-Wheel g.

a3 is an index or pointer attached to and moving with the arbor carryingthe crown- Wheel a.

Z) is an idle crown-Wheel normally retained in position by a detent ZJand adapted to mesh with a single tooth b2, projecting radially from theWheel a.

c is a crown-Wheel normally retained in position by means of a detent cand adapted to mesh witha single tooth c2, projecting ra dially from theidle-wheel b.

c3 is an index 0r pointer attached to and moving With the arbor carryingthe croWn- Wheel c.

Z, Z', and Z2 are respectively the hon-r, minute, and second hands of aclock, of which the Works are contained in a receptacle Zo, formed inthe housing e and located in rear of the partition c3, and therespective hands exposed to view are caused to traverse the dial n inthe usual manner by means of the arbor and sleeves o, o', and o?,passing through the sleeve e6.

IOO

In practice the number of teeth upon the ratchet-wheel g will dependupon the "diameter of the wheel B, the object being to cause theratchet-wheel g to revolve once for each sixteenth of a mile traversedby the vehicle.

In ,the present instance, by reference to the drawings, it is to beassumed that the diameter of the wheel B is thirty inches. Consequentlythe ratchet -Wheel g is provided with fortyfour (44) teeth. It should,however, be borne in mind that if a larger. or smaller vehiclewheel isemployed a correspondingly dierent ratchet-Wheel g must be employed. Thecrown-wheel a is provided with sixteen teeth, and consequently isadvanced one tcoth for each sixteenth of a mile traversed bythe vehicle,and makes one complete revolution for each mile traversed thereby, andthe index or pointer asindicates the distance traversed in quarter,half, and three-quarter miles upon the dial n3. The idle-wheel b isprovided with ten teeth or pins and `is advanced one tooth for everymile traversed by the vehicle,

so that the same makes one complete revolution for every ten milestraversed by the ve hicle. The crown-wheel c is advanced one tooth foreach revolution of the idle-wheel b, and consequently for each ten milestraversed by the vehicle, and the indexv or pointer i c3 will indicatethe distance traversed in multiples of ten miles upon the dial m3,whereby the rider may readily ascertain the distance gone and the timeconsumed. in going thatE distance by simply inspecting the dials. It@may be remarked that the idle-Wheel ccauses both of the indices orpointers to revolvein the Q same direction, thus facilitating theoperation of reading the distance traversed on the,

cyclometer.

I-n cases where a greater number of miles than one thousand is to berecorded an additional Wheel driven by an idle-Wheel may be employed.This duplication of the wheels, it will be readily understood, may-beextended as required. e

It will bc obvious to those skilled in the art to which myinventionappertains that the distance traversed by a vehicle may be recorded intenths or in any other preferred' anism, as described, for actuating thehands,

a sleeve communicating with the interior of 'said housing, aratchet-wheel mounted on thel sleeve and provided with a finger meshingattached to said hands, substantially as shown and described. 2. Thecombination of a housing provided with dials, a train ofrecording-wheels mounted on arbors, indices attached to said arbors, a-

sleeve, a ratchet-Wheel mounted on a shaft and provided with a fingerengaging one of said train of Wheels, a lever mounted on said.

shaft and provided with a spring-actuated pawl engaging saidratchet-Wheel, and a spring attached to said lever and housing,substantially as shown and described.

3. The combination of a housing provided with dials, a train ofrecording-wheels comprising crown-wheels provided with an extra tooth ordog, indices attached to certain of said crown-wheels, a sleeve, aratchet-wheel provided with a finger, aspring-controlled leverprotruding through said housing and mounted on said sleeve, and a pawlattached to said lever and adapted to engage said ratchet-wheel,substantially as shown and described.

4. The combination, with the front fork and Wheel of a bicycle,tricycle, or velocipede, of a lug attached to said wheel, a housingattached to said fork and provided with dials,

a train of recording-wheels and indices therefor, a sleeve, aratchet-Wheel for actuating said train of Wheels, and aspring-controlled lever mounted on said sleeve and having one extremityprotruding through said housing and adapted to contact with said lugandhaving the other extremity provided with a pawl, substantially as andfor the'purposes set forth.

5. The combination ofl a vehicle-Wheel provided with a lug, a stationaryhousing provided with dials, a train of recording-wheels and indices, asleeve, a ratchet-Wheel for actuating said train, la spring-controlledlever mounted on said sleeve and adapted to con- IOO tact with said lugat each revolution of the wheel, and a pawl attached to said lever andadapted to engage said ratchet-wheel, substantially as and for thepurposes set forth.

In witness whereof I have hereunto set my signature in the presence oftwo Witnesses.
